Portable Scale Stand Assembly With Locking Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scale stand assemblies for overhead weighing lack the ability to adjust height and move around different positions efficiently, making it difficult to weigh structures and items at various locations without repositioning the items themselves.
Innovation Solution
A portable scale stand assembly comprising a base, an articulating arm assembly with a locking member and biasing member, and a scale platform, which allows for adjustable height positioning and movement via wheels, enabling the scale to be easily repositioned for weighing at different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the scale stand assembly is made portable with wheels for moving around different positions, then the ease of operation is improved, but the stability of the assembly may be compromised
Solution Approach 1:
The base is designed with wheels to enable dynamic movement when needed, while the articulating arm assembly provides adjustable positioning that can be locked in place. This combination allows the assembly to transition between mobile and stable states, resolving the contradiction between ease of moving and stability.
2Adaptability or versatility
If the articulating arm assembly allows slidable movement between lowered and raised positions for height adjustment, then the adaptability is improved, but the reliability of position locking may be compromised
Solution Approach 1:
The locking member is pre-configured to engage with the articulating arm assembly at specific positions. Before the arm reaches a desired height, the locking mechanism is ready to secure it, ensuring reliable position locking while maintaining height adjustability. The biasing member also pre-positions components to facilitate smooth movement and secure locking.
Solution Approach 2:
The locking member acts as an intermediary between the articulating arm assembly and the base, providing a mechanical connection that secures the arm at desired positions. This intermediary component enables both movement during adjustment and reliable locking during use, resolving the contradiction between adaptability and reliability.
3Ease of operation
If the biasing member is added to provide biasing force between upper and lower components, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The biasing member is designed to automatically provide the necessary force for articulation without requiring external intervention. It self-regulates the movement between the upper and lower components, making the assembly easier to operate while adding only one component rather than a complex mechanism, thus minimizing the increase in device complexity.
